[0028] One of the said stool support 2 is provided with a through hole 9 and a straight slot 8, the straight slot 8 is communicated with the through hole 9, the through hole 9 is provided with symmetrical pins 11, the symmetrical pins 11 are fixedly connected with sliding rods 12 respectively, the symmetrical sliding rods 12 are arranged in the straight slot 8 respectively, the stool backrest 5 is provided with symmetrical positioning holes 10, and the symmetrical pins 11 are matched with the symmetrical positioning holes 10.

[0029] The symmetrical pins 11 are fixedly connected with retaining springs 13 respectively.

[0030] Two stool supports 2 are connected through a bandage, and two vertical rods of the stool backrest 5 are connected through a bandage.

[0031] In the embodiment one, the symmetrical polygonal shafts 21 are fixedly connected with the corresponding foot pedals 1 respectively.

[0032] The working principle of the portable lower limb rehabilitation training device is as follows:

[0033] In the initial state, the two stool supports 2 are close to each other, and the pins 11 are extended out of the through holes 9.

[0034] The stool support 2 is swung to open the stool support 2, and the stool support 2 drives the upper shaft 6, the pin 11, the sliding rod 12, the retaining spring 13, the stool backrest 5, the handle 4, the upper rotating wheel 14, the upper connecting rod 15, the upper synchronous belt 16, the double rotating wheel 17, the lower synchronous belt 18, the lower connecting rod 19, the lower rotating wheel 20, the polygonal shaft 21 and the foot pedal 1 to swing, so that the stool support 2 is opened.

[0035] The user sits on the straps connecting the stool support 2, with their back against the straps on the stool backrest 5. They step on the foot pedal 1, hold the handle 4, and swing the handle 4. The handle 4 drives the upper rotating wheel 14 to rotate, which in turn drives the double rotating wheel 17 to rotate via the upper synchronous belt 16. The double rotating wheel 17, in turn, drives the lower rotating wheel 20 and the polygonal shaft 21 to rotate reciprocally via the lower synchronous belt 18. The polygonal shaft 21 drives the foot pedal 1 to swing back and forth, and the foot pedal 1 drives the lower limbs to swing back and forth, thus achieving lower limb rehabilitation training.

[0036] Example 2: The symmetrical foot pedals 1 are each provided with polygonal holes 22 that match the polygonal axis 21. By using polygonal holes 22, the relative position of the foot pedals 1 and the handles 4 can be easily adjusted, allowing the user to maintain a comfortable posture during exercise.

[0037] The working principle of the lightweight lower limb rehabilitation training device provided by this utility model is as follows:

[0038] In the initial state, foot pedal 1 and handlebar 4 are as follows: Figure 1 As shown. The stool supports 2 are close to each other, and the pin 11 extends out of the through hole 9.

[0039] Swing the stool support 2 to open it. The stool support 2 drives the upper shaft 6, pin 11, slide rod 12, retaining spring 13, stool backrest 5, handle 4, upper rotating wheel 14, upper connecting rod 15, upper synchronous belt 16, double rotating wheel 17, lower synchronous belt 18, lower connecting rod 19, lower rotating wheel 20, polygonal shaft 21, and foot pedal 1 to swing, thus opening the stool support 2. Move the slide rod 12 so that the pin 11 enters the through hole 9, compressing the retaining spring 13. Swing the stool backrest 5, causing the handle 4, upper rotating wheel 14, upper connecting rod 15, upper synchronous belt 16, double rotating wheel 17, lower synchronous belt 18, lower connecting rod 19, lower rotating wheel 20, polygonal shaft 21, and foot pedal 1 to swing, so that the pin 11 matches the positioning hole 10, allowing the pin 11 to be inserted into the positioning hole 10, and the retaining spring 13 to return to its original position.

[0040] The user sits on the straps connecting the stool support 2, with their back against the straps on the stool backrest 5. The user removes the foot pedal 1 from the polygonal shaft 21, swings the handle 4 to position their hands comfortably, and inserts the foot pedal 1 back onto the polygonal shaft 21. The user steps on the foot pedal 1, grips the handle 4, and swings the handle 4. The handle 4 drives the upper rotating wheel 14 to rotate, which in turn drives the double rotating wheel 17 via the upper synchronous belt 16. The double rotating wheel 17, via the lower synchronous belt 18, drives the lower rotating wheel 20 and the polygonal shaft 21 to rotate reciprocally. The polygonal shaft 21 causes the foot pedal 1 to swing back and forth, and the foot pedal 1 causes the lower limbs to swing back and forth, thus achieving lower limb rehabilitation training.
